What Determines the Value of a Diamond?
Two diamonds that appear similar can have very different values.
Diamond pricing depends on much more than carat weight alone. A professional evaluation considers the individual characteristics of the diamond along with current demand for that particular type of stone.
Carat Weight
Carat refers to the weight of a diamond.
Larger diamonds generally command higher prices, but diamond value does not increase at a perfectly even rate. Certain carat-weight thresholds can have a meaningful effect on market demand.
Not sure of your diamond's carat weight? Our Diamond Size & Carat Weight Calculator can help you estimate approximate carat weight from millimeter measurements and compare typical sizes for the most common diamond shapes.
Cut
Cut affects how effectively a diamond interacts with light and can significantly influence its appearance and desirability.
Proportions, symmetry, polish and overall cutting quality may all be relevant.
Color
For traditional colorless diamonds, less visible body color is generally more desirable.
Fancy-color diamonds are evaluated differently. Their market can depend on the strength, rarity and character of the color.
Clarity
Clarity describes internal and external characteristics within a diamond.
The type, size, number and location of inclusions can influence both grading and marketability.
Shape
Round brilliant diamonds often trade differently from oval, cushion, emerald, pear, marquise, princess and other shapes.
Demand for individual diamond shapes can change over time.
Certification
A grading report from a respected gemological laboratory, particularly the Gemological Institute of America (GIA), can make a diamond's characteristics easier to verify and may improve marketability.
Certification is helpful, but you do not need a grading report to bring us your diamond.
Natural vs. Laboratory-Grown Diamonds
Natural and laboratory-grown diamonds currently trade in very different secondary markets.
Determining whether a diamond is natural or laboratory-grown is therefore an important part of the evaluation process.
Current Market Demand
Ultimately, the resale market for a diamond depends on current demand for that particular combination of size, quality, shape and other characteristics.
Diamond markets change, which is why an older appraisal or original retail price does not necessarily represent today's resale value.

What Diamonds Does Joseph Diamonds Buy?
Joseph Diamonds purchases diamonds in many forms, sizes and styles.
Loose Diamonds
We evaluate certified and uncertified loose natural diamonds during private appointments.
Diamond Engagement Rings
We purchase modern and vintage engagement rings, including solitaire settings, halo rings, three-stone rings, designer engagement rings and other diamond ring styles.
Wedding Sets
Joseph Diamonds purchases diamond wedding sets, anniversary rings, eternity bands and other wedding jewelry.
Estate & Inherited Diamonds
Inherited diamond jewelry may contain pieces from different generations and periods, with widely varying levels of quality and value.
If you're unsure what you inherited, you do not need to identify or research every piece before your appointment.
Antique & Old-Cut Diamonds
Older jewelry may contain diamond cuts that differ significantly from modern brilliant-cut stones.
These can include:
- Old European Cut diamonds
- Old Mine Cut diamonds
- Transitional Cut diamonds
- Antique cushion-shaped diamonds
- Other historic cutting styles
Older diamonds may require a different evaluation approach from modern stones because their cutting style, proportions and collector appeal can affect how they trade.
Designer Diamond Jewelry
Diamond jewelry from recognized luxury houses may have additional value based on the maker, design, condition and current secondary-market demand.
If your diamond is part of a larger estate or inherited collection, visit our Estate Jewelry Buyer in Kansas City page.
Selling a Diamond Engagement Ring?
Engagement rings are among the most common diamond pieces we evaluate.
The value of an engagement ring may come from several components, including:
- Center diamond
- Side diamonds
- Gold or platinum setting
- Designer or maker
- Condition
- Diamond certification
- Current secondary-market demand
In some rings, most of the value is concentrated in the center diamond.
In others, the setting, designer, antique construction or overall piece may also deserve consideration.
If you have the original grading report, box, receipt or other documentation, bring it with you. If the paperwork is missing, we can still evaluate the ring.

Selling an Inherited Diamond?
Inherited diamonds can be difficult to evaluate because families often have little information about the stone.
You may not know:
- The carat weight
- Whether the diamond is natural or laboratory-grown
- Its color or clarity
- Whether it is certified
- Whether the setting has additional value
- Whether the jewelry is antique or designer
You don't need to know those answers before contacting Joseph Diamonds.
We can examine the diamond and the jewelry containing it, explain the characteristics we see and provide an offer if we're interested in purchasing the piece.
If the diamond is part of a larger inheritance, consider bringing the entire collection rather than trying to determine which items are valuable beforehand.
Certified & Uncertified Diamonds
Do I Need a GIA Report to Sell My Diamond?
No.
A GIA grading report can be extremely useful because it provides an independent description of the diamond's characteristics, but many diamonds arrive without paperwork.
If you have a GIA report or another laboratory grading report, bring it with you.
If you don't have one, Joseph Diamonds can still examine the diamond.
Already Have an Offer for Your Diamond?
Get a Second Opinion Before You Sell
Diamond offers can vary because buyers may have different inventory needs, resale markets and opinions about a particular stone.
If you've already received an offer from another diamond buyer, jewelry store, pawn shop or gold buyer, you're welcome to bring your diamond to Joseph Diamonds for an independent evaluation.
We'll examine the diamond ourselves and provide our own offer.
There is no obligation to sell.

Diamond Jewelry May Be Worth More Than the Diamond Alone
When a diamond is mounted in jewelry, we evaluate the complete piece whenever appropriate.
Additional value may come from:
- Designer or maker
- Side diamonds
- Natural gemstones
- Gold or platinum setting
- Antique construction
- Period design
- Condition
- Rarity
- Current secondary-market demand
For signed, antique or important estate jewelry, the complete piece can sometimes be more desirable than simply separating the diamonds from the mounting.
That's why Joseph Diamonds considers the jewelry as a whole rather than automatically evaluating every piece solely for its components.
Insurance Appraisal vs. Diamond Resale Value
An insurance appraisal does not necessarily represent the amount a diamond will sell for in the secondary market.
Insurance appraisals are commonly prepared for replacement purposes and may use retail replacement values that differ substantially from current resale-market pricing.
An appraisal can still contain useful information about the diamond, so bring it with you if you have one.
The actual resale evaluation should be based on the diamond itself and current market conditions.
